Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 3,306,245, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 3,306,245 | |
| -1 | -3,306,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,306,245.
Example:
1 x 3,306,245 = 3,306,245
and
-1 x -3,306,245 = 3,306,245
Notice both answers equal 3,306,245
With that explanation out of the way, let's continue. Next, we take the number 3,306,245 and divide it by 2:
3,306,245 ÷ 2 = 1,653,122.5
If the quotient is a whole number, then 2 and 1,653,122.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,306,245 | |
| -1 | -3,306,245 |
Now, we try dividing 3,306,245 by 3:
3,306,245 ÷ 3 = 1,102,081.6667
If the quotient is a whole number, then 3 and 1,102,081.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,306,245 | |
| -1 | -3,306,245 |
Let's try dividing by 4:
3,306,245 ÷ 4 = 826,561.25
If the quotient is a whole number, then 4 and 826,561.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,306,245 | |
| -1 | 3,306,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 401 | 485 | 1,649 | 2,005 | 6,817 | 8,245 | 34,085 | 38,897 | 194,485 | 661,249 | 3,306,245 |
| -1 | -5 | -17 | -85 | -97 | -401 | -485 | -1,649 | -2,005 | -6,817 | -8,245 | -34,085 | -38,897 | -194,485 | -661,249 | -3,306,245 |
